Linezolid use in Medicin Therapy against Multiresistant Bacteria-A Review

Abstract

After the description of an element with ability to combat the infectious processes originating from bacteria, starts a race for survival between the interrelationship of species, bacterial and human. With the evolution scientifictechnical, the man was able to synthesize new antibacterial substances, on the other hand the mechanisms of gene evolution enabled the emergence of multidrug-resistant bacteria. Some of this organisms are frequent on hospital environment and have high adaptability to new drugs, such as Staphylococcus aureus and Enterococcus spp. resistant to oxacillin and vancomycin, considered drugs of choice against multidrug-resistant microorganisms. So, a new antibiotics class was developed, superior to vancomycin and oxazolidinone, the linezolid. Thus, the present study aimed at understanding the use of linezolid in drug therapy against multi-resistant bacteria. To perform this study, a literature review of last 10 years was performed. In 2002, after the liberation of the use of linezolid as treatment for infectious processes against gram-positive bacteria, this drug was commonly used throughout the world. Similarly, the pressure of natural selection stood out, and there were records of resistant strains to linezolid. As prospects for control of infections caused by these resistant strains, was approved by the FDA in 2014 the use of drugs with linezolid resistant anti-strains activity. However, we conclude that, in addition to natural selection and genetic variation process, human behavior regarding the use of antibiotics, increases the selection of resistant microorganisms to antibiotic, including linezolid.
